We are not going to deceive you: the dog is an animal very sweet who takes every opportunity to take a bite of everything that he considers must have an exquisite taste. But most of the time it is very important that we ignore it, since otherwise we could end up having an overweight furry.
Although this behavior is still curious, so let's see why is my dog always hungry.
You are not being given the amount of food you need
And let's start with the basics: food. Whether you feed it as natural food it is very important that you give him the amount he needs. In the first case, in the same bag he will put the amount, but if you give him fresh meat, you have to give him the amount that is equivalent to 2-3% of his weight if he is an adult (if it is a puppy, it would be 6-8 %). You do not have to give him more or less, except if he is very thin or on the contrary with a few extra kilos, in which case I would recommend consulting a veterinarian to tell you how much you should give him.
Have anxiety or stress
As with people, dogs can overeat when they are anxious or stressed. To get him to be calm again, it is convenient take him out for a walk every day, play a lot with him to burn all that energy, and spend as much time as possible with him to make you feel safe.
If you are very nervous or restless, do not hesitate to ask a canine ethologist for help.
He is weak in health
It is rare, but it can happen. If your dog has suddenly started looking for food at all hours, and if he also has other symptoms such as excessive thirst, listlessness or weight loss, it is advisable to see a veterinary professional as soon as possible for examination, as you could have diabetes or gastric problems.
Our friends, dogs, already have a sweet tooth, but sometimes that gluttony can be a sign of illness, so we must always be attentive to any changes that occur in their routine.
